EXPANSION DEVICE FOR FURNITURE.

Application filed June 21,

To all whom it may concern Be it known that I, HERMAN E. SoHNnr- DER, citizen of U. S. A., residing at Spring Valley, in the county of Rockland and State of New York have invented new and useful Improvements in Expansion Devices for Furniture ()1 which the following is a specifieation.

This invention relates to expansion devices for furniture and the principal object is to provide means whereby the rungs of chairs or tables may be securely fastened in the mortiees in which they are seated.

Another object is to produce a device of this nature which shall be simple of construction, cheap to manufacture, and highly efficient for the purpose for which it is designed. 7

With these and other objects in view which will be more apparent asthe specification proceeds, the invention resides in certain novel construction and combination and arrangement of parts the essential features of which are hereinafterfullydescribed, are particularly pointed out in the appended claims, and are illustrated in the accompanying drawing in which Figure l is a side elevation of my improved securing device.

Figure 2 is an end elevation of the same.

Figure 3 is a fragmentary view of a rung provided with one of my improved devices and ready to be inserted into the mortice.

Like characters of reference refer to like parts in all views.

Referring to the drawing in detail. a strip of sheet metal 10 is bent into a LL shape so as to have a curved bottom 11, and then the ends of the legs of the member 10 are returned on themselves as at 12 and are reduced so as to form spurs 13. Small V-shape portions 1 1 are cut and ex- Specification of Letters Patent.

tended at each side of the device and two small strips 15 are inserted in the spurs 13 as shown in the drawing.

In use the rung of a chair or table or like piece of furniture such as shown at 16 is provided with a pair of slots or kerfs 17 in its end and into these kerfs the portions 12 of member 10 are entered. Spurs 13 are then placedin the mortice 18 of the chair or table leg 19 and the parts are driven to gether. In this manner the spurs 13 are driven into the member 19 and extended laterally of the mortice 18 at the same time the folded portions 12 are advanced into the kerfs 17 and the said spurs 141 will prevent easy withdrawing of the rung. The strips 15 will also be driven into the slots 17 and will so thoroughly expand the end of the rung into the mortice 18 as to prevent withdrawal even under very great stress.

lVhat is claimed is 1. in device of-the class described comprising a piece of sheet metal bent to form a U-shaped body portion and having its ends returned and formed into the diverging spurs.

2. A device of the class described comprising'a piece of sheet metal bent to form a U-shaped body portion and having its ends returned and formed into the diverging spurs, and spurs formed out from the outer faces of said metal near the point where the return is effected.

3. A device of the class described comprising a strip of metal bent so as to form a U-shape body portion and diverging spur portions and strips between said body portion and said spur portions.

In testimony whereof I have aiiixed my signature.

HERMAN E. SCHNEIDER.
